My understanding is that `Shuffle My Music`, will make a queue of 50 songs from favorited tracks, albums, and playlists, and then when that queue finishes, it will add more songs.

If `Automated recommendations` is toggled on, it will continue with a mix of favorites and some discovery (non-favorites). 

If `Automated recommendations` is toggled off, it will continue with only more favorites.

I would prefer `Automated recommendations` toggle to include discovery tracks in the initial queue. If the user is open to hearing discovery music mixed in, why wait until the 50 song initial queue is done to play the mix?
